Goliath is a Philistine warrior in the Book of Samuel. Descriptions of Goliath's immense stature vary among biblical sources, with the Masoretic Text describing him as 9 feet 9 inches (2.97 m) tall. According to the text, Goliath issued a challenge to the Israelites, daring them to send forth a champion to engage him in single combat; he was ultimately defeated by the young shepherd David, employing a sling and stone as a weapon. The narrative signified King Saul's unfitness to rule, as Saul himself should have fought for Israel.
